Argument for Assault guns

OK.OK. I know the ordinary person doesn't need an assault weapon, but there are exceptions to every rule. Let's say a person wanted to kill a large number of coyotes that had killed a dozen chickens and a couple of precious turkeys and were around her horses. Realistically, you couldn't reload fast enough if they decided to charge. They are pack animals-wild and unpredictable. Kinda like a mildly, irrational female.
